Abstract: This application provides a channel encoding method and apparatus in wireless communications. The method includes: performing CRC encoding on A to-be-encoded information bits, to obtain a first bit sequence, where the first bit sequence includes L CRC bits and A information bits; performing a interleaving operation on the first bit sequence, to obtain a second bit sequence, where a first interleaving sequence used for the interleaving operation is obtained based on a system-supported maximum-length interleaving sequence with the length of Kmax+L, and Kmax is a maximum information bit quantity corresponding to the maximum-length interleaving sequence ad a preset rule, and a length of the first interleaving sequence is equal to A+L. Therefore, during distributed CRC encoding, when an information bit quantity is less than the maximum information bit quantity, an interleaving sequence required for completing an interleaving process is obtained based on the system-supported maximum-length interleaving sequence.

Abstract: Embodiments of this application provide a method and an apparatus for constructing a sequence of polar codes. In an implementation, a tectonic sequence P′ is read from a tectonic sequence P, where the length of the tectonic sequence P′ is an encoding length M and the length of the tectonic sequence P is N. The tectonic sequence P′ is demapped to a reliability ranking sequence Q′ based on a rate matching rule, and K elements that have largest reliability values is read from the reliability ranking sequence Q′, to obtain an information bit sequence number set A.

Abstract: Embodiments of polar encoding/decoding methods and apparatuses are described. CRC encoding is performed on an information block to obtain a CRC encoded block with a length of B, where a CRC length is Lcrc, an information block length is K, and B=K+Lcrc. The CRC encoded block is interleaved. Lpc CRC bits in the interleaved encoded block are located between bits of the information block. Each CRC bit of the Lpc CRC bits is located after all bits checked by using the CRC bit. Lpc is an integer greater than 0 and less than Lcrc. The interleaved encoded block is mapped to information bits. A frozen bit is set to an agreed fixed value. Polar encoding is performed on the information bits and the frozen bit to obtain a polar encoded codeword to improve performance of a CA-polar code.

Abstract: A method includes: obtaining first semantic information corresponding to data; converting the first semantic information into second semantic information, where the second semantic information belongs to common semantic information, and the common semantic information is a unified description of same semantics that is provided by different devices; and sending the second semantic information. Based on the method provided in this application, when a semantic extraction model of a transmit device and a semantic understanding model of a receive device are not jointly trained, accuracy of semantic communication between the transmit device and the receive device may be ensured by converting local semantic information into common semantic information.
